Flow cytometry overlay histogram showing wild-type Raji (green line) and CXCR5 knockout Raji cells (ab273380) stained with ab254415 (red line). The cells were incubated in 1x PBS containing 10μg/ml human IgG and 10% normal goat serumto block FC receptors and non-specific protein-protein interaction followed by the antibody (ab254415) (1x106 in 100μl at 0.2 μg/ml) for 30 min at 4°C.
The secondary antibody Goat anti-rabbit IgG H&L (Alexa Fluor® 488, pre-adsorbed) (ab150081) was used at 1/2000 for 30 min at 4°C.
Isotype control antibody was Rabbit IgG (monoclonal) (ab172730) used at the same concentration and conditions as the primary antibody (wild-type Raji - black line; CXCR5 knockout Raji - grey line). Unlabelled sample was also used as a control (this line is not shown for the purpose of simplicity).
Acquisition of >5000 events were collected using a 50 mW Blue laser (488nm) and 525/40 bandpass filter.

Immunohistochemical analysis of paraffin-embedded human tonsil tissue labeling CXCR5 with ab254415 at 1/5000 dilution followed by ready to use Rabbit specific IHC polymer detection kit HRP/DAB (ab209101). Positive staining on human tonsil (PMID: 12393412). The section was incubated with ab254415 for 10 mins at room temperature. The immunostaining was performed on a Leica Biosystems BOND® RX instrument. Counterstained with Hematoxylin.
Secondary antibody only control: Secondary antibody is ready to use Rabbit specific IHC polymer detection kit HRP/DAB (ab209101).
Heat mediated antigen retrieval with Citrate buffer (pH 6.0, epitope retrieval solution 1) for 20 mins.

Predicted band size: 42 kDaLanes 1 - 4: Merged signal (red and green). Green - ab254415 observed at 60 kDa. Red - loading control ab7291 (Mouse anti-Alpha Tubulin [DM1A]) observed at 55 kDa.
ab254415 was shown to react with CXCR5 in Raji wild-type cells in Western blot with loss of signal observed in CXCR5 knockout sample. Wild-type and CXCR5 knockout Raji cell lysates were subjected to SDS-PAGE. Membranes were blocked in fluorescent western blot (TBS-based) blocking solution before incubation with ab254415 and ab7291 (Mouse anti-Alpha Tubulin [DM1A]) overnight at 4 °C at a 1 in 1000 dilution and a 1 in 20000 dilution respectively. Blots were incubated with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 h at room temperature before imaging.

ab254415 staining CXCR5 in Daudi cells (top panel, positive control) and Jurkat cells (bottom panel, negative control). The cells were fixed with 4% paraformaldehyde (10 min) then permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated with ab254415 at 5μg/ml concentration and ab7291 (Mouse monoclonal to alpha Tubulin) at 1/1000 dilution overnight at 4°C followed by a further incubation at room temperature for 1h with a goat secondary antibody to rabbit IgG (Alexa Fluor® 488) (ab150081) at 2 μg/ml (shown in green) and a goat secondary antibody to mouse IgG (Alexa Fluor® 594) (ab150120) at 2 μg/ml (shown in red). Nuclear DNA was labelled in blue with DAPI.
Image was taken with a confocal microscope (Leica-Microsystems TCS SP8). -
Flow cytometric analysis of Raji (Human Burkitt's lymphoma B lymphocyte) cells labelling CXCR5 with ab254415 at 1/500 dilution (0.1µg) (Red) compared with a Rabbit monoclonal IgG (ab172730) (Black) isotype control and an unlabelled control (cells without incubation with primary antibody and secondary antibody) (Blue). Goat anti rabbit IgG (Alexa Fluor® 488, ab150077) at 1/2000 dilution was used as the secondary antibody. Gated on viable cells.

Goat anti rabbit IgG (Alexa Fluor® 488, ab150077) was used as the secondary at a 1/2000 dilution. Cells were stained with rabbit IgG (Left) or ab254415 (Right), then stained with anti-CD19 conjugated to Alexa Fluor® 647.
Gated on viable cells.
